Benefits of technology

The invention is a new type of drill tip for displacement piles that is stronger and more efficient than existing tips. It has a conical shape with more teeth and cutting blades, which means it can better penetrate soil. The drill tip is also designed to reduce heat and is streamlined. This improvement allows for easier handling and use of smaller drilling rigs. The invention also has a picking eye and tabs for alignment during manufacturing, which make it easier to attach to a steel pipe. Overall, the new drill tip improves the process of displacement piles and makes it more efficient and cost-effective.

Problems solved by technology

Further, the conically shaped drill tip has a more severe angle of impact to reduce heat.

Embodiment Construction

[0025]A FDPT constructed of steel from top to bottom prevents fracturing and saves costs. The FDPT contains at least four-fish tails 1 which means that a hardened steel tip with more steel is at the initial penetration point into the ground. The fish tails are at the cutting end of the drill tip. Two piece steel casting 2 is more cost efficient than rolled steel. The FDPT is attached to a steel pile 9 (not part of the invention) and screwed into the ground. The whole apparatus including the FDPT and steel pier stays in the ground preventing the hole from caving in. The operator simply drills the FDPT and steel pier into the ground and disconnects. Because the whole apparatus is left in the ground, shorter piers can be used, and less time is consumed. “Pier” and “pile” mean the same thing.

[0026]Steel teeth can be arrayed in three flights called cutting teeth, 3, 6 and 8, with the lower flight 8, the middle flight 6, and the upper flight 3. The flights of teeth are wider at the cuttin...

Abstract

The device is a Full Displacement Pile Tip (FDPT) with a sacrificial drill bit that is connected to a steel pipe, where the tip comprises at least four flanges or fish tails at the cutting edge extending from a conical, dome-like bottom, and integrally connected to the cutting teeth along the tip's axial shaft. The purpose of the FDPT is allow a steel pier to be screwed into the ground to serve as a foundation for a structure. This is a single operation where the FDPT and pipe remain in the ground. There is no removal of FDPT, minimal pouring of concrete, and there is minimal soil spoilage. A smaller drilling rig can be employed to save operating costs.

Description

CROSS-REFERENCE[0001]claim priority to a provisional application No. 61 / 827,889, filed May 28, 2013.STATEMENT REGARDING FEDERAL SPONSORED RESEARCH[0002]None.PARTIES TO JOINT RESEARCH AGREEMENT[0003]None.BACKGROUND OF THE INVENTION[0004]The Full Displacement Pile Tip (FDPT) is a drilling bit that is very effective in penetrating many types of soil in order to install a steel pier for building foundation support. The FDPT is so efficient in laterally displacing soil that the concrete required to supplement the installation is minimal and soil waste is minimal. This speeds up construction at reduced costs.[0005]Support is crucial in the construction of a building. Where soil is loose or cannot be adequately compressed to support the building, then deep holes are drilled under the foundation and concrete is typically poured into holes for reinforcement. Further, where hardened bedrock is located beneath the building, then a very sturdy bit is required to penetrate the rock as an anchor....
